[4] Recent stylistic tendencies have moved away from an earlier abstract style, exemplified in works such as Ptolemy's Onion, towards what the composer terms a more "corporeal" approach embracing tangible references to existing music and a highly physical performance aesthetic.
Although Ricketson's materials are eclectic, often including disparate processes within the one work, Gordon Kerry describes his music as aesthetically late-modernist in that it is "experimental in form and speculative in content".
[10] Ricketson's Ptolemy's Onion received the Marienberg Spring Award for an Outstanding Australian Composition and was subsequently chosen for the Gaudeamus International Music Week.
Ricketson has received commissions from: Warsaw Autumn International Festival of Contemporary Music; the Transit Festival (Belgium); The Song Company; the Australian Chamber Orchestra; Symphony Australia; Continuum Sax; ABC Classic FM; the Portuguese-based Drumming Grupo de Percussão, the MLC School Burwood, Speak Percussion and piano soloist Zubin Kanga.
[10] Ricketson has been artist-in-residence at the Banff Centre, Canada; the Bundanon Estate (Shoalhaven); the University of Wollongong and the Peggy Glanville-Hicks House (Sydney).
